I've settled into every other day, extremely low volume, high intensity, and high frequency. For me, this is the best balance of quick (1 hour max) and fun (intensity) that pairs well with growth, strength, and cutting. 2-way split with some fullbody in both. Still believe the "best" program you can do is not the one with optimal growth and timing, but the one that you do and enjoy consistently (first and foremost) and with continual progress in numbers or reps.
I love the gym, but anything more than AB x AB x (x = off day) doesn't work well with me.
I can't say anything on rhabdomyolysis, but it sounds serious enough to reconsider a new training program and see if it helps.
Sleep.. 8 hours ideally, 7 usually.
